To ALL WHOM 1T M AY CONCERN; v u Y v v Be it known that I, FREI-)BRICK W. BROWN, of Philadelphia, Pennsylvania, have invented a Device for Soldering and Unsolderinfg` the Lids of- Fruit-Cans, dto.; and I do .hereby declare the following to be a full, clear, and exact description of the same. 1

My invention consists in the combination, substantiallyas described hereafter, of ametal block, a sharpened instrument, and a chain, the whole forming a device for facilitating the soldering or unsoldering of the covers offruit-cans, inthe manner hereinafter explained.' l v n f l In order to enable others .to make and use my invention, I will'now proceed to describe its construction and operation, reference being had to thel accompanying drawing, which 'forms-a part of this specification, and

Figure 1 is a side view'of my device for soldering-and.unsoldering the lids of fruit-cans, 83e., and v Figure 2 a plan view ofthe same.

A is a circular block, of cast iron orctlier suitable metal, and is flatv on the under side, and rounded, or of'Y other convenient form, on the top, where there is an eye, I1, to which is att-acheda chain, C, serving to connect the block to a steel instrument, D, the end, c, of which' is attenedand sharpensd,.for a purpose described hereafter.

The block A is somewhat smaller indiameter than the cover, y, of the fruit-can, (shoivn by red lines,) and:

when it is required to solder this cover to the can, the block is heated and'placed upon Vthe centre of the lid, as shown in the drawing. v ,I l

Resin, or other equivalent material-,fisvtbon sprinlled npon, the cover, ncar its' edge, and the end of a bar of solder is passed Aaround the same, in contact with-the heated -block A, the latter melting the solder, and at theY same time serving as a guide; for the `bar, and "the desired dntyot'soldering the cover tothe. can being` thus' performed with much greater rapidity than'by the usual soldering-iron.

After thus soldering the cover, the block is removed to another can,and the operation` repeated until theV lblock becomes cool, when it is again heated` for further usc. Y

In opening cans, the heated block is permitted to rest upon the cover y until the solder which secures it to lid, and the latter is easily raised and removed. v

It will be observed that the instrument D performs the twofold duty of serving as a handle,-by which the heated block may be manipulated, and as a tool for aiding in the removal ofthe cover. I

I claim as my invention, and desire to secure by Letters Patent- I The combination, substantially as described, ot' the block A, vinstrument D, and chain C, for the purpose specilied. l

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

F. W. BROWN.

the can is melted, then the flat'and'sharpened end, o, oi the instrument D is'inserted beneath the edgeof the Witnesses:
